May I add something with respect to your first question. I would just like to state that when we talked about $18 billion in collection accounts, that referred to non-challenged accounts. Accounts where an objection has being filed represent an additional $6 billion. The audit focused on accounts where there was no notice of objection.
With respect to your last question, I would say that the reason is simply that we had a series of audits to do with the agency and at the Department of Revenue at the time. Given the scope and complexity of the operations, it took some time before we got back to the collection service. That was not necessarily because some systems have been put in place, but rather because that was in keeping with the work plan.
